If your cats are getting more wet food than you put out, maybe you could reduce the dry to 1/4 to 1/3 of a cup to share for even healthier results.
I've been feeding my cats wet food 3 times a day. My goal is to reduce dry food to such a small portion that it's only a treat. I've been reading a lot about the evils of dry food. And no, I would never tell anyone not to feed it. That's up to the individual cat owner. But based on what I've been learning I feel the need to protect my cats. My father's cat has been in the hospital for a couple days due to UTI issues. My dad and his wife have a dry food buffet out for their cats 24 hours a day. I've been reading Dr Pitcairn's Guide to Natural Care for Dogs and Cats and I've learned some more stuff. Cats that get UTI's usually have been fed a predominantly dry diet all their lives. Dr Pitcairn tells people to make a point, "If you want your cats to get bladder problems, just put down dry food and leave it out all the time." Most cats who get kidney failure later in life have had UTI issues when they were younger. There are consequences of prescription dry diets for UTI issues. They acidify the urine but mask the problem and leech calcium from the bones. Also it's easier to detect warning signs of kidney disease with a cat on a wet food diet than a dry food diet. A cat on a 100% canned food diet almost never drinks. Warning signs of kidney diseae are increased thirst. So if a cat that eats predominantly or 100% wet food drinks a lot of water that could be a sign of kidney disease. With a dry diet it's hard to tell because cats on predominantly or all dry food diets are forced to drink water. Dr Pitcairn also said that cats by nature eat infrequently and it's not natural for them to have access to food all the time as in the case of free feeding and free feeding increases the risk of UTIs. And that it's ok if a cat refuses his breakfast or dinner to wait until the next meal to feed him as cats who are fed twice a day are living in luxury.
So reducing dry food and increasing the wet food even further can be even more beneficial.
